Experts discuss effects, misconceptions of GMOs

Print More

A panel of experts on genetically modified crops explained the effects of GMOs and contradicted common misconceptions about GMOs during a public conversation March 8.

The Midwest Center for Investigative Reporting, CU-CitizenAccess and the Knight Chair of Investigative Reporting, Journalism Department at the College of Media, University of Illinois Urbana-Champaign co-hosted the event held at the Champaign Public Library.

Speakers from the University of Illinois College of Agricultural, Consumer and Environmental Sciences (ACES) and the University of Illinois Extension Office, among others, discussed what GMOs do today, their impact on our environment and economy and their next stages.

The five-person panel, “Talking GMOs,” lasted about an hour and a half.

Among the speakers:


Leia Flure, a dietician with the University of Illinois extension, said she often hears concerns about GMOs from her customers, including that GMOs cause autism, cancer and allergies.

Leia Flure is a registered dietitian working in the field of nutrition education. She strongly believes that all foods can (and should!) be included in a healthy, balanced lifestyle and is passionate about helping consumers make informed food choices that work for them. Flure earned her Bachelor's degree in Psychology and Master's degree in Nutritional Sciences, both from the University of Illinois at Urbana-Champaign. She has previously worked as an Instructor Agricultural Communications and as a Nutrition and Wellness Educator with University of Illinois Extension. Talking GMO event on Wednesday, March 8, 2017.

But Flure said that there has been no credible evidence to back up these claims and stressed the role of the consumer in finding reliable information.

She said that many of these claims have to do with causation-correlation issues, such as that as GMO crops have increased, so has the ability to detect and diagnose autism and allergies.

Gray said that Bt corn is so effective that its use has become widespread, which leads to other issues.

Gray said that the insect has started to develop resistance to Bt corn and stressed the need for integrated pest management, or a combination of different methods to handle pest control.

Gray said that it may be beneficial for farmers to decrease use of Bt crops because the number of insects its killing are below significant risk levels.

Dr. Michael E. Gray served as a professor of Agricultural Entomology and as an Extension Entomologist with the Department of Crop Sciences, University of Illinois. He also provided leadership for the Agricultural and Natural Resources Extension Program as an Assistant Dean, College of ACES. He was president of the Entomological Society of America (ESA) in 2008 and is a fellow and honorary member of that professional society. His research focused on the management of the western corn rootworm, a significant insect pest of corn throughout the Midwest.

Jack Murray, a fifth-generation farmer and seed corn salesman, said that during his decades as a farmer, he’s seen the benefit of GMOs on farmers, specifically by increasing yield and decreasing pesticide use.

“In the past, we were over spraying,” Murray said. “Today we’re doing it in the seed. We’re not polluting the water by spraying on acres that are non-targeted (for pests).”

Murray said farming of the future will depend on technology.

“We’ve got to increase our production 40 percent by 2050,” he said. “We’re not gonna do it by farming the way we did 40 years ago.”

Tamara Nelsen, senior director of commodities of the Illinois Farm Bureau, said that humans have been modifying genes for thousands of years, but they have been more effective in doing so as technology has improved.

Nelsen gave the example of the arctic apple, a type of apple that will take much longer to brown than regular apples because it removes the browning gene. She said changes like that and adding Vitamin A to Golden Rice make food healthier and last longer.

Paul South, a researcher for the USDA and the University of Illinois, said his work focuses on increasing the yield of crops by making the photosynthesis process more efficient.

South said that in order to feed larger populations in the future, yields will need to increase and that effects everyone.

“Yields translate when you go to the grocery store,” South said. “I’m also a family man. I want a safe and secure food supply. I also want a cheap food supply. Food prices will go down because there are more food products on the market.”

He received his Ph.D. in Biochemistry from Purdue University while working on gene regulation in cholesterol biosynthesis in 2012. Currently, he works on improving photosynthetic efficiency with the goal of making plants produce more on less land. He has lived in Champaign for four years and is married with three children.
